The game console 176 sends audio to the audio subsystem 110 via link(s) 122 (e.g., S/PDIF for digital audio or “line out” for analog audio). Additional details of an example audio subsystem 110 are described below.

FIG. 1B is a diagram that depicts an example gaming audio subsystem comprising a headset and an audio basestation, in accordance with various exemplary embodiments of the disclosure. Referring to FIG. 1B, there is shown a console 176, a headset 200 and an audio basestation 301. The headset 200 communicates with the basestation 301 via a link 180 and the basestation 301 communicates with the console 176 via a link 122. The link 122 may be as described above. In an example implementation, the link 180 may be a proprietary wireless link operating in an unlicensed frequency band. The headset 200 may be as described below with reference to FIGS. 2A-2C. The basestation 301 may be as described below with reference to FIGS. 3A-3B.

FIG. 1C is a diagram of an exemplary gaming console and an associated network of peripheral devices, in accordance with various exemplary embodiments of the disclosure. Referring to FIG. 1C, there is shown is the console 176, which is communicatively coupled to a plurality of peripheral devices and a network 106. The example peripheral devices shown include a monitor 108, a user interface device 102, a headset 200, an audio basestation 301, and a multi-purpose device 192.

The monitor 108 and the user interface device 102 are as described above. The headset 200 is as described below with reference to FIGS. 2A-2C. The audio basestation is as described below with reference to, for example, FIGS. 3A-3B.

The multi-purpose device 192 may comprise, for example, a tablet computer, a smartphone, a laptop computer, or the like and that runs an operating system such as Android, Linux, Windows, iOS, OSX, or the like. An example multi-purpose device is described below with reference to FIG. 4. Hardware (e.g., a network adaptor) and software (i.e., the operating system and one or more applications loaded onto the device 192) may configure the device 192 for operating as part of the GPN 190. For example, an application running on the device 192 may cause display of a graphical user interface (GUI), which may enable a user to access gaming-related data, commands, functions, parameter settings, and so on. The graphical user interface may enable a user to interact with the console 176 and the other devices of the GPN 190 to enhance the user's gaming experience.

The peripheral devices 102, 108, 192, 200, 301 are in communication with one another via a plurality of wired and/or wireless links (represented visually by the placement of the devices in the cloud of GPN 190). Each of the peripheral devices in the gaming peripheral network (GPN) 190 may communicate with one or more others of the peripheral devices in the GPN 190 in a single-hop or multi-hop fashion. For example, the headset 200 may communicate with the basestation 301 in a single hop (e.g., over a proprietary RF link) and with the device 192 in a single hop (e.g., over a Bluetooth or Wi-Fi direct link), while the tablet may communicate with the basestation 301 in two hops via the headset 200. As another example, the user interface device 102 may communicate with the headset 200 in a single hop (e.g., over a Bluetooth or Wi-Fi direct link) and with the device 192 in a single hop (e.g., over a Bluetooth or Wi-Fi direct link), while the device 192 may communicate with the headset 200 in two hops via the user interface device 102. These example interconnections among the peripheral devices of the GPN 190 are merely examples, any number and/or types of links and/or hops among the devices of the GPN 190 is possible.

The GPN 190 may communicate with the console 176 via any one or more of the connections 114, 140, 122, and 120 described above. The GPN 190 may communicate with a network 106 via one or more links 194 each of which may be, for example, Wi-Fi, wired Ethernet, and/or the like.

The gaming audio data may comprise, for example, signatures of particular audio clips (e.g., individual sounds or collections or sequences of sounds) that are part of the game audio of particular games, of particular levels/scenarios of particular games, particular characters of particular games, etc. In an example implementation, the database 182 may comprise a plurality of records 183, where each record 183 comprises an audio clip (or signature of the clip) 184, a description of the clip 185 (e.g., the game it is from, when it occurs in the game, etc.), one or more gaming commands 186 associated with the clip, one or more parameter settings 187 associated with the clip, and/or other data associated with the audio clip. Records 183 of the database 182 may be downloadable to, or accessed in real-time by, one of more devices of the GPN 190.

FIGS. 2A and 2B are diagrams that depict two views of an example embodiment of a game headset, in accordance with various exemplary embodiments of the disclosure. Referring to FIGS. 2A and 2B, there are shown two views of an example headset 200 that may present audio output by a gaming console such as the console 176. The headset 200 comprises a headband 202, a microphone boom 206 with microphone 204, ear cups 208 a and 208 b which surround speakers 216 a and 216 b, connector 210, connector 214, and user controls 212.

The connector 210 may be, for example, a 3.5 mm headphone socket for receiving analog audio signals (e.g., receiving chat audio via an Xbox “talkback” cable).

The microphone 204 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to convert acoustic waves (e.g., the voice of the person wearing the headset) to electric signals for processing by circuitry of the headset and/or for output to a device (e.g., console 176, basestation 301, a smartphone, and/or the like) that is in communication with the headset.

The speakers 216 a and 216 b may comprise circuitry that may be operable to convert electrical signals to sound waves.

The user controls 212 may comprise dedicated and/or programmable buttons, switches, sliders, wheels, etc. for performing various functions. Example functions which the controls 212 may be configured to perform include: power the headset 200 on/off, mute/unmute the microphone 204, control gain/volume of, and/or effects applied to, chat audio by the audio processing circuit of the headset 200, control gain/volume of, and/or effects applied to, game audio by the audio processing circuit of the headset 200, enable/disable/initiate pairing (e.g., via Bluetooth, Wi-Fi direct, NFC, or the like) with another computing device, and/or the like. Some of the user controls 212 may adaptively and/or dynamically change during gameplay based on a particular game that is being played. Some of the user controls 212 may also adaptively and/or dynamically change during gameplay based on a particular player that is engaged in the game play. The connector 214 may be, for example, a USB, thunderbolt, Firewire or other type of port or interface. The connector 214 may be used for downloading data to the headset 200 from another computing device and/or uploading data from the headset 200 to another computing device. Such data may include, for example, parameter settings (described below). Additionally, or alternatively, the connector 214 may be used for communicating with another computing device such as a smartphone, tablet compute, laptop computer, or the like.

FIG. 2C is a diagram that depicts a block diagram of the example headset of FIGS. 2A and 2B, in accordance with various exemplary embodiments of the disclosure. Referring to FIG. 2C, there is shown a headset 200. In addition to the connector 210, user controls 212, connector 214, microphone 204, and speakers 216 a and 216 b already discussed, shown are a radio 220, a CPU 222, a storage device 224, a memory 226, and an audio processing circuit 230.

The radio 220 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to communicate in accordance with one or more standardized (such as, for example, the IEEE 802.11 family of standards, NFC, the Bluetooth family of standards, and/or the like) and/or proprietary wireless protocol(s) (e.g., a proprietary protocol for receiving audio from an audio basestation such as the basestation 301).

The CPU 222 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to execute instructions for controlling/coordinating the overall operation of the headset 200. Such instructions may be part of an operating system or state machine of the headset 200 and/or part of one or more software applications running on the headset 200. In some implementations, the CPU 222 may be, for example, a programmable interrupt controller, a state machine, or the like.

The CPU 222 may also be operable to handle in-game visualization processing for the headset 200 based on, for example, analysis of game and/or chat audio received from the console 176 during game play. The CPU 222 may also be operable to handle in-game visualization processing for the headset 200 based on, for example, information in game and/or chat audio that is present specifically for the purpose of generating in-game visualization, rather than for the purpose of presentation to a listener. For example, information in the game and/or chat audio may indicate a game being played such that a corresponding visualization may be generated, a type of visualization to be generated (e.g., whether to display a map or a radar image), the content of the visualization (e.g., which characters and/or things to display on a map or radar image), how frequently the visualization should be updated, whether audio alerts should accompany the visualization, and/or the like. In this regard, the CPU 222 may be operable to dynamically handle processing of in-game visualizations for the headset 200 based on information that may be received from the audio processing circuit 230 and/or information that may be stored in the storage device 224 or an external storage device.

The storage device 224 may comprise suitable logic, circuitry, interfaces and/or code that may comprise, for example, FLASH or other nonvolatile memory, which may be operable to store data comprising operating data, configuration data, settings, and so on, which may be used by the CPU 222 and/or the audio processing circuit 230. Such data may include, for example, parameter settings that affect processing of audio signals in the headset 200 and parameter settings that affect functions performed by the user controls 212. For example, one or more parameter settings may determine, at least in part, a gain of one or more gain elements of the audio processing circuit 230. As another example, one or more parameter settings may determine, at least in part, a frequency response of one or more filters that operate on audio signals in the audio processing circuit 230. As another example, one or more parameter settings may determine, at least in part, whether and which sound effects are added to audio signals in the audio processing circuit 230 (e.g., which effects to add to microphone audio to morph the user's voice). Example parameter settings which affect audio processing are described in the co-pending U.S. patent application Ser. No. 13/040,144 titled “Game headset with Programmable Audio” and published as US2012/0014553, the entirety of which is hereby incorporated herein by reference. Particular parameter settings may be selected autonomously by the headset 200 in accordance with one or more algorithms, based on user input (e.g., via controls 212), and/or based on input received via one or more of the connectors 210 and 214.

The storage device 224 may also be operable to store audio information resulting from analysis of the plurality of audio channels of game and/or chat audio during game play. In one embodiment of the disclosure, the headset 200 may be operable to download the audio information for a particular game from a sounds database in an external storage device and store the downloaded audio information in the storage device 224. The external storage device may be located at a remote server (e.g., database 182 in FIG. 1C) or may be an external memory device, for example. In this regard, the CPU 222 may be operable to configure the radio 220 to download the audio information for the particular game. The audio information may comprise sounds and/or corresponding voice commands for the particular game, which may be utilized to provide in-game visualizations. Upon subsequent playback of that particular game, the headset 200 does not need to download the audio information for that particular game from the sounds database but may instead acquire the audio information for that particular game from the storage device 224. The CPU 222 may be operable to ensure that any updates to the sounds database may be downloaded from the sounds database and saved in the storage device 224 to ensure that the audio information and sounds for the particular game is kept up-to-date.

In another embodiment of the disclosure, the CPU 222 may be operable to configure the audio processing circuit 230 to perform signal analysis on the audio signals on one or more of the plurality of audio channels that are received via the connector 210 and/or the radio 220. The CPU 222 may be enabled to control the operation of the audio processing circuit 230 in order to store the results of the audio analysis along with, for example, an identifier of the game in the storage device 224. The CPU 222 may be enabled to monitor the plurality of audio channels that are received via the connector 210 and detect the characteristics of one or more sounds. Based on the detected sounds, the CPU 222 may be operable to generate a visual representation of the detected sounds and/or their corresponding characteristics (an “in-game visualization”). The CPU 222 may be operable to extract the one or more voice commands that correspond to the detected sounds from the internal storage device 504 b.

In an exemplary embodiment of the disclosure, audio information for a particular game may be stored in a lookup table (LUT) in the storage device 224. In this regard, the LUT may comprise an identity of the game, audio information corresponding to a detected sound and a corresponding visual representation may be mapped to the detected sounds. In instances when a sound is detected on a monitored channel, the CPU 222 may compare the detected sound to that audio information that is stored in the storage device 224. If the comparison results in a match between the detected sound and the stored audio information, the corresponding visual representation may be determined from the LUT and output for display.

In an example implementation, the console 176 supports overlaying an in-game visualization on the screen on which the game itself is being played or on a second screen connected to the console. In such an implementation, the visual representation may be output to the console 176.

In an example implementation, the headset 200 may generate the video stream corresponding to the in-game visualization and output the video to the device 192 (i.e., treating the device 192 as a simple monitor).

In an example implementation, the headset 200 may work in concert with the device 192 to generate the in-game visualization. In such an implementation, for example, the headset 200 may send data resulting from analysis of game and/or chat audio to the device 192 (e.g., via an API of an in-game visualization app running on the device 192) and the device 192 may use that data to generate the video stream corresponding to the in-game visualization.

In some embodiments of the disclosure, the basestation 300 (FIG. 1B) may be operable to provide connectivity between the headset 200, the console 176 and the user interface devices 102, 103 which may comprise a game controller and the second screen communication device. In this regard, the basestation 300 may be operable to handle communication of the visual representation to the second screen communication device and/or to the console 176.

The memory 226 may comprise suitable logic, circuitry, interfaces and/or code that may comprise volatile memory used by the CPU 222 and/or audio processing circuit 230 as program memory, for storing runtime data, and so on. In this regard, the memory 226 may comprise information and/or data that may be utilized to control operation of the audio processing circuit 230 to perform signal analysis on the analysis of a plurality of received audio channels of game and/or chat audio in order to detect the characteristics of one or more sounds in the game and/or chat audio.

The audio processing circuit 230 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to perform audio processing functions such as volume/gain control, compression, decompression, encoding, decoding, introduction of audio effects (e.g., echo, phasing, virtual surround effect, etc.), and/or the like. As described above, the processing performed by the audio processing circuit 230 may be determined, at least in part, by which parameter settings have been selected. The processing performed by the audio processing circuit 230 may also be determined based on default settings, player preference, and/or by adaptive and/or dynamic changes to the game play environment. The processing may be performed on game, chat, and/or microphone audio that is subsequently output to speaker 216 a and 216 b. Additionally, or alternatively, the processing may be performed on chat audio that is subsequently output to the connector 210 and/or radio 220.

The audio processing circuit 230 may be operable to perform signal analysis on received audio signals that carry a plurality of audio channels. In this regard, the audio processing circuit 230 may be operable to analyze the audio on each of the plurality of received audio channels in order to detect the characteristics of sounds corresponding to the audio signals. In an exemplary embodiment of the disclosure, the audio processing circuit 230 may be operable to analyze the audio on each of the plurality of received audio channels in order to detect a unique signature that may be associated with a certain sound.
